A gas station in Manila, Philippines charges 38.46 pesos per liter for gasoline when a US dollar (USD) is equal to 47.15 pesos (PHP). The car you are driving has a gas tank of 34.5 U.S. gallons and gets 24.3 miles per gallon. a. What is the cost of the gasoline in Manila in USD/gallon? b. How much would a tankful of gasoline cost in USD? c. Suppose you have only 1255 PHP and the car's tank is almost empty. How many miles can you expect to drive if you spend all your money on gasoline?
A well-insulated mixing heat exchanger operating steadily at 3 bar receives water at 300 °C and 4 m/s through an inlet of diameter 12 cm, and water at 75 °C and 0.25 m/s through a second inlet of 2 cm diameter. The outlet is 9 cm diameter. Find the outlet velocity in m/s and the rate at which entropy is generated by the heat exchanger in kW K^-1.
